Celebrating the Community: OpenSSF at Open Source Summit and OpenSSF Community Day Europe Recap

From August 25–28, 2025, the Linux Foundation hosted Open Source Summit Europe and OpenSSF Community Day Europe in Amsterdam, bringing together developers, maintainers, researchers, and policymakers to strengthen software supply chain security and align on global regulations like the EU Cyber Resilience Act (CRA). The week included strong engagement at the OpenSSF booth and sessions on compliance, transparency, proactive security, SBOM accuracy, and CRA readiness. 

OpenSSF Community Day Europe celebrated milestones in AI security, public sector engagement, and the launch of Model Signing v1.0, while also honoring five community leaders with the Golden Egg Awards. Attendees explored topics ranging from GUAC+Trustify integration and post-quantum readiness to securing GitHub Actions, with an interactive Tabletop Exercise simulating a real-world incident response. 

These gatherings highlighted the community’s progress and ongoing commitment to strengthening open source security. Read more.

Open Source Friday with OpenSSF – Global Cyber Policy Working Group

On August 15, 2025, GitHub’s Open Source Friday series spotlighted the OpenSSF Global Cyber Policy Working Group (WG) and the OSPS Baseline in a live session hosted by Kevin Crosby, GitHub. The panel featured OpenSSF’s Madalin Neag (EU Policy Advisor), Christopher Robinson (CRob) (Chief Security Architect) and David A. Wheeler (Director of Open Source Supply Chain Security) who discussed how the Working Group helps developers, maintainers, and policymakers navigate global cybersecurity regulations like the EU Cyber Resilience Act (CRA). 

The conversation highlighted why the WG was created, how global policies affect open source, and the resources available to the community, including free training courses, the CRA Brief Guide, and the Security Baseline Framework. Panelists emphasized challenges such as awareness gaps, fragmented policies, and closed standards, while underscoring opportunities for collaboration, education, and open tooling. 

As the CRA shapes global standards, the Working Group continues to track regulations, engage policymakers, and provide practical support to ensure the open source community is prepared for evolving cybersecurity requirements. Learn more and watch the recording.

Improving Risk Management Decisions with SBOM Data

SBOMs are becoming part of everyday software practice, but many teams still ask the same question: how do we turn SBOM data into decisions we can trust? 

Our new whitepaper, “Improving Risk Management Decisions with SBOM Data,” answers that by tying SBOM information to concrete risk-management outcomes across engineering, security, legal, and operations. It shows how to align SBOM work with real business motivations like resiliency, release confidence, and compliance. It also describes what “decision-ready” SBOMs look like, and how to judge data quality. To learn more, download the Whitepaper.

Trustify joins GUAC

GUAC and Trustify are combining under the GUAC umbrella to tackle the challenges of consuming, processing, and utilizing supply chain security metadata at scale. With Red Hat’s contribution of Trustify, the unified community will serve as the central hub within OpenSSF for building and using supply chain knowledge graphs, defining standards, developing shared infrastructure, and fostering collaboration.

Recap: OpenSSF Community Day India 2025

On August 4, 2025, OpenSSF hosted its second Community Day India in Hyderabad, co-located with KubeCon India. With 232 registrants and standing-room-only attendance, the event brought together open source enthusiasts, security experts, engineers, and students for a full day of learning, collaboration, and networking.

The event featured opening remarks from Ram Iyengar (OpenSSF Community Engagement Lead, India), followed by technical talks on container runtimes, AI-driven coding risks, post-quantum cryptography, supply chain security, SBOM compliance, and kernel-level enforcement. Sessions also highlighted tools for policy automation, malicious package detection, and vulnerability triage, as well as emerging approaches like chaos engineering and UEFI secure boot.

The event highlighted India’s growing role in global open source development and the importance of engaging local communities to address global security challenges. Read more.

New OpenSSF Guidance on AI Code Assistant Instructions

In our recent blog, Avishay Balter, Principal SWE Lead at Microsoft and David A. Wheeler, Director, Open Source Supply Chain Security at OpenSSF introduce the OpenSSF “Security-Focused Guide for AI Code Assistant Instructions.” AI code assistants can speed development but also generate insecure or incorrect results if prompts are poorly written. The guide, created by the OpenSSF Best Practices and AI/ML Working Groups with contributors from Microsoft, Google, and Red Hat, shows how clear and security-focused instructions improve outcomes. It stands as a practical resource for developers today, while OpenSSF also develops a broader course (LFEL1012) on using AI code assistants securely. 

This effort marks a step toward ensuring AI helps improve security instead of undermining it. Read more.

Open Infrastructure Is Not Free: A Joint Statement on Sustainable Stewardship

Public package registries and other shared services power modern software at global scale, but most costs are carried by a few stewards while commercial-scale users often contribute little. Our new open letter calls for practical models that align usage with responsibility — through partnerships, tiered access, and value-add options — so these systems remain strong, secure, and open to all.

Signed by: OpenSSF, Alpha-Omega, Eclipse Foundation (Open VSX), OpenJS Foundation, Packagist (Composer), Python Software Foundation (PyPI), Rust Foundation (crates.io), Sonatype (Maven Central).
